[SECURE] File Send was created for a simple purpose: to send files to people quickly and securely. While there are a lot file upload programs out there, none of the simple ones allowed you to upload over an SSL connection. This was frustrating to us because we send sensitive files all the time.

So this is how it works: you upload a file, then you get a special URL that works for 24 hours. There is also a limit of 50MB per file.
